This document describes issues of interest related to migration from the TMS320VC549 to the TMS320VC5409. The objective of this document is to indicate differences between the two devices. Functions that are identical between the two devices are not included. For detailed information on the specific functions of either device, refer to the device data sheets and/or the TMS320C54x DSP CPU and Peripherals, Reference set, Volume 1 (SPRU131).
Migration issues from the VC549 to VC5409 are indicated with the following symbols, which are included at the beginning of each section:
[S] means software modification is required.
[H] means hardware modification is required.
[D] means the VC549 and VC5409 are different (usually due to added features on theVC5409), but no modification is necessary for migration (that is, the devices are different but compatible).
